Rise Armament RA-100F Two-Stage Trigger | Flat Blade | Black
The Rise Armament RA-100F Two-Stage Trigger | Flat Blade is a practical AR trigger upgrade built for shooters who want a cleaner, more predictable pull without moving into premium trigger pricing. Designed as a durable component-style trigger for AR-15 and AR-10 platforms with standard small-pin milspec dimensions, the RA-100 combines a flat trigger blade, two-stage control, and rugged construction for training, competition, duty, and general range use.
This Rise Armament RA-100F two-stage trigger uses a 4.5 lb. total pull weight with an approximate 1.5 lb. first stage and 3 lb. second stage. The first stage allows deliberate take-up before reaching a defined wall, while the second stage provides a clean break that helps improve shot control compared to a standard milspec fire control group. The flat blade gives the shooter a consistent indexing surface and a straight-back press feel that many prefer for precision-focused AR builds.
RISE Armament machines the RA-100F from heat-treated S7 tool steel for long-term strength and wear resistance. A black nitride finish adds corrosion resistance, surface hardness, and easier cleanup, making this flat blade trigger well suited for high-round-count training rifles and hard-use carbines. The forceful hammer spring is engineered for reliable primer ignition, including use with steel-cased ammunition.
Installation is streamlined compared to many traditional component triggers. The disconnector is pre-assembled, reducing loose parts and simplifying setup while still using included milspec hammer and trigger pins. For builders looking for an affordable two-stage AR trigger with a predictable break, tactile reset, and broad AR-platform compatibility, the Rise Armament RA-100 Two-Stage Trigger | Flat Blade offers a strong balance of value, control, and durability.
The RA-100F is especially useful for shooters upgrading from a gritty milspec trigger who want improved consistency without an overly light pull. Its two-stage design supports deliberate precision work, controlled cadence during drills, and confident use across recreational, training, competition, and professional applications.
